In the present study, reinforced concrete beams are considered for the calculation of minimum flexural reinforcement, Moment-Curvature relationship and ductility index using fracture energy. Normal strength concrete i.e. M20, M30, M40, M50 and high strength concrete i.e. M60, M70, M80, M90, M100 are considered in this experiment with the varying grade of steel from Fe250, Fe415, Fe500. In a particular grade of concrete, minimum flexural reinforcement is decreased with the increase in grade of steel. In a particular grade of steel, minimum flexural reinforcement is increased with the increase in the grade of concrete. Ductility Index is decreased with the increase in grade of concrete. Similar trend is observed when fracture energy is not considered in calculation of minimum percentage of reinforcement.
